What evidence establishes a nonconforming animal rights use in Utah? Carlsen v. Board of Adjustment of the City of Smithfield Explained

In Carlsen v. Board of Adjustment of the City of Smithfield, the Utah Court of Appeals examined what evidence suffices to establish an existing nonconforming animal rights use and the standards governing judicial review of such administrative decisions.

Background and Facts

The Smiths owned property that was rezoned from agricultural to residential in 1970. In 2009, they petitioned the Board of Adjustment to recognize an existing nonconforming animal rights use for keeping cattle on the property. The Smiths asserted that cattle had been continuously kept on the property since before the rezoning, satisfying the city code requirement that animals must be present for at least thirty days per calendar year to maintain the nonconforming use. Neighbor D. Craig Carlsen contested the petition, challenging both the existence of the use and whether it had been abandoned.

Key Legal Issues

The case presented several issues: whether substantial evidence supported the Board’s finding of continuous nonconforming use since 1970, whether Carlsen properly marshaled evidence supporting the Board’s decision, and whether various procedural challenges were preserved for appeal. Additional issues included alleged bias of a board member and the timeliness of the Smiths’ intervention in district court proceedings.

Court’s Analysis and Holding

The court applied the substantial evidence standard to the Board’s quasi-judicial decision, explaining that such decisions are not arbitrary and capricious if supported by evidence adequate to convince a reasonable mind. The court found that multiple letters from long-term residents and testimony from the Smiths and previous owners constituted substantial evidence of continuous cattle presence since 1970. Critically, the court noted that Carlsen failed to properly marshal the evidence supporting the Board’s decision, instead selectively citing facts favorable to his position while ignoring contradictory evidence.

Practice Implications

This decision reinforces the marshaling requirement for parties challenging administrative decisions. Attorneys must present all evidence supporting the agency’s decision and demonstrate why it remains insufficient despite supporting facts. The court also clarified that boards have discretion in weighing conflicting evidence and resolving ambiguities. Additionally, the case demonstrates the importance of preservation of error—several of Carlsen’s arguments were rejected because he failed to raise them before the Board. For intervention practice, the decision shows courts will consider the totality of circumstances, including administrative delays, when determining timeliness.
